Windows 10 Insider Preview – GSOD Whilst Updating – aksdf.sys Error

Green screen of death

Have you been struggling to install the latest Windows 10 Insider Preview?

Been getting a green screen of death (GSOD) about 70% into the process?

Well I decided to do a bit of digging and found out that this process ( aksdf.sys ) belongs to a USB dongle driver. I can’t even remember the last time any software I used needed a security dongle, let alone use one now!

Note: Obviously, if you do use any software that may use the hasp sentinel driver described below, it may be worth checking with the software provider first to see if they have a patch etc. to help. You could also just re-install the driver after updating Windows.

I found a web page detailing how to uninstall this driver. I downloaded the tool and uploaded it to this website for ease.

Firstly, download the following file:../downloads/

Then unzip the file within ( haspdinst.exe ) to your C: (You will need administrator rights to do so).

Open an administrative command prompt (click start, type cmd, right-click Command Prompt and click ‘Run as Administrator’.)

Make sure you are at the root of C drive (you should see C: at the bottom of the command prompt window). If you aren’t and see some other letter, type C: and press enter.

Then copy and paste the following into the Command Prompt window and press return:

haspdinst.exe -kp -r -fr -v -purge

The Sentinel install window will appear for a short time and should come back successful. You can then try updating Windows again which should happily fly past the 70% mark and complete.

Please leave a comment if this has helped you!

  1. OMG I can’t thank you enough for this. I spent literally all day yesterday trying. I tried everything(thought I did) including cleaning the registry, uninstalling programmes, you name it. Each time, the windows update would last for around 25-30mins before spitting the above error. After using your method of clearing that driver, the update sped through and was done in about 10mins or less. AMAZING!!! And thanks again!!

    1. Hi Jerry, thanks so much for the comment, good to know it is actually helping people out there! I was in the boot loop and lost a lot of hair in the process! Thanks again, Dave.

  2. Echoing what Jerry said Dave. Sorted my problem out as well. Thanks for researching and publishing the solution to this problem. Saved my from losing another day of my life. THanks again !!.

    1. That’s great news Eddie! I didn’t know if it was going to be a one off as I do like to mess about with my PC but glad it is acutally helping people. You’re more than welcome!

  3. Thank you so much for the instructions and the uninstaller. I was a little reluctant to download the files from the sentinel web site and it wasnt real clear. This also addressed my issues with upgrading and getting the green screen of death. In my case I received the aksdf.sys file when I installed xrite monitor calibrator software. Unistalling xrite didnt uninstall these drivers until i ran the haspdint.exe.

    Thank you

  4. Starting to despair of ever getting my Dll T3600 to upgrade Win 7 pro to Win 10 pro, and then googled aksdf.sys and found your amazing website. Downloaded the tool followed your instructions and here I am up and running in Windows 10 Pro. Thank you so much!!!!!
